BOBBIN-STANID FOR LOOM-MAGAZINES.

Specification of Letters Patent. Patented Jan. 2, 1917.

Application filed January 24, 1916. Serial No. 73,839.

To all whom it may concern:

Be it known that we, WILLIAM FRANKLIN KING and JOHN SIDNEY lVIIITLooK, citizens of the United States of America, and residents of Clinton, county of Laurens, State of South Carolina, and Laurens, county of Laurens, State of South Carolina, respectively, have invented certain new and useful Improvements in Bobbin-Stands for Loom- Magazines, of which the following is a full and clear specification.

This invention relates to that class of looms in which a magazine or battery of bobbins is provided for automatically supplying the shuttles with bobbins, this type of loom being well known as the Draper or Northrop weft-replenishing loom. I

In the drawingsFigure 1 is a side elevation of a hopper stand constructed in ac cordance with our invention; Fig. 2 is an elevation of the opposite side of the lower part of the hopper stand; and Fig. 3 is a detail perspective view of a detachable part of the hopper stand hereinafter described.

In the drawing, a designates the usual disk-like hopper stand which is cast integral with a pedestal b for rigidly supporting the hopper disk upon the breast beam of the loom. The bobbins are delivered by Well known mechanism from this hopper stand to the shuttles. The bobbins are forced by the transferrer hammer through a throat consisting of a stationary guide 0 and a tiltable supporting guide shown in dotted lines at (Z, a bobbin being shown in my drawing at e. The tiltable guide (Z is usually pivoted in an eye bearing f and is maintained in its normal position by a well known form of spring actuating device which embodies a bolt or rod which is adapted to slide back and forth between the outwardly projecting lugs arranged just above the bearing f. The construction of all the foregoing parts is well known and they, therefore, need not be described more in detail.

Heretofore, the guide lugs or ears '9 as well as the eye bearing f have been cast integral with the bobbin disk or stand. These ting the casting but also necessitating the stopping of the loom long enough to substitute a new stand. It is the object of our invention to provide means whereby in case of breakage of the lugs or the bearing, the stand may be repaired and thus be continued in use.

In our device, the lugs and the bearing are formed integral with a separate metal plate h which fits into a radial notch 2' formed in the edge of the disk-like stand, this plate 72. being provided with longitudinal flanges 7' along its opposite edges which are adapted to fit against the outer face of the disk and be riveted thereto. The plate It has its inner face flush with the inner face of the disk at, but its outer face projects beyond the outer face of the disk to the extent of the thickness of the flanges j, and the longitudinal edges of the plate It fit closely against the side walls of the notch 2', so that when the plate it is riveted firmly to the disk, the full strength of the disk is maintained. Should the bearing f or the lugs g be broken, the fastening rivets may be readily cut off and a new plate inserted and riveted into place, thus avoiding the necessity of junking the entire stand structure and also greatly saving in the time required to repair the stand. Our invention is particularly adapted for repairing the old type of stand now in general use in which the bearing and the lugs are cast in tegral with the stand. When breakage occurs with this old type of stand, it is our practice to saw out the ear and the lugs by cutting a radial notch in the stand, a suitable templet or pattern being used to insure the notch being the proper size to exactly fit the plate h and also to insure the proper location of the lugs and the bearing when the new plate is inserted. In this way it will be seen that by providing loom owners with a supply of the separately formed plates h and a suitable patternor templet, the owners may readily repair broken stands and thus avoid a great waste that heretofore was deemed to be inevitable with this 'class of looms.

lugs and the bearing f frequently become It will be understood that the insert h J shattered or broken and, in view of the fact that the entire stand is cast integral, the I stand has to be junked. thus not only wastmay be either cast or forged.

e claim is:

1. loom hopper stand or disk having a Having thus described our invention, What radial notch formed in the edge of the stand adjacent to the bobbin throat, a plate fitted into this notch and detachably fastened therein, this plate being provided with supporting and guiding means for the usual tiltable member of the bobbin throat.

2. A patch for loom stands consisting of a plate adapted to fit into a notch formed in the stand of the bobbin magazine and provided with means for supporting the tiltable member of the bobbin throat.

3. A patch for loom magazine stands consisting' of a plate flanged along the edges of its outer face and provided with an integral eye bearing at its outer end and with integral guide lugs on its outer face, for the purpose set forth.

4. A patch for loom magazine stands consisting-of a plate formed with integral lateral flanges along the edges of its outer face and provided with an integral eye bearing at its outer end and with integral guide lugs on its outer face, whereby when said patch is inserted in a notch of similar shape formed in the edge of the'stand the plate will bridge the notch and have its side edges abutting against the edge walls of the notch and its lateral flanges bearing against the outer face of the stand.

5. A loom hopper stand having a substantially radial notch formed in its edge adjacent to the bobbin throat, a plate inserted in this notch and having its side edges abutting the edge walls of the notch and its inner face flush with the inner face of the stand, said plate being provided along the edges of its outer face with lateral flanges which over lap upon the outer face of the stand, means being provided for securing the plate to the stand through the medium of said flanges, said plate being provided on its outer face with an, integral eye bearing and with integral guide lugs.

In testimony whereof we hereunto aflix our signatures this 21st day of January,

7 his WILLIAM FRANKLIN KING.
